In the J2 League, FC Machida Zelvia emerged victorious for the first time, along with its first promotion to the J1 League. Head coach Go KURODA, who has produced numerous successes as a prominent licensed coach in the world of senior high school football, was invited for this season. Efforts to review defence, reinforce the team with talented foreign players, and boost the growth of young players, were effective. Since rising to the top position in the 10th section in April, it continued to reign with stable play, entering the top two spots in the 39th section to satisfy one of the criteria for promotion, and securing its win in the 40th section. This marked a significant leap forward from the previous season when it was ranked 15th. In addition, Jubilo Iwata, which moved up to the second position in the final game and Tokyo Verdy, which conquered the J1 Promotion Play-Offs, were both restored to the J1 League after one year and 16 years respectively.

In the J3 League, Ehime FC took its first win and was restored to the J2 League for the first time in three years. It did not relinquish this top position from the 17th section in July, securing its promotion in the 35th section with three sections to go, along with the champion title. Under the guidance of head coach Kiyotaka ISHIMARU, who was taking command of the team for the second time since 2022 after concluding his player career in Ehime, the team was reinforced through the combined forces of experienced veteran players such as Ryota MORIWAKI and Riki MATSUDA, and young players such as Shunsuke TANIMOTO and Taiga ISHIURA. Out of 21 victories, the team achieved 19 of these with a one-point lead, demonstrating their competitive strengths and ultimately dominating the league. On the other hand, the other promotion spot was taken by Kagoshima United FC. It secured the second place in the final section and made its return to the J2 League for the first time in five years.
